I'm part of this theatre thing on Gaia and there's this one dude that drives me up a freaking wall. He's been in a few plays at his school so he thinks he is the expert at theatre but he is the most unprofessional actor I've ever met.
He finds something wrong with almost every performance we've done so far (he's only been in two productions, I entered the production before him and I can tell you I wouldn't have come back if he was part of the cast that I entered the group in) and he sits there giving "advice" about what to do on stage like he's from Broadway or something. His attitude just stinks, period. One time we were right in the middle of a rehearsal when he comes in 30 minutes late, sees that barely anyone was there, and starts whining that he doesn't think he should rehearse since no one was there.
Edit: Okay, I went to rehearsal yesterday and before the director showed up he was bragging to this girl that was new about all he did during his first production and told her that he played most of the characters. Which he didn't, he subbed for a couple of people but he wasn't actually in those roles. If he's counting subbing for people as actually playing that part, I played his part in one production more than he did because he was barely there on performance nights.
Okay, now I'm done ranting.
